To put it simply, the Radeon X800GT isn't any one new core, or even a cut-down version of any one old core. Instead, Radeon X800 GT boards can made up of either R423, R430 or R480 cores left over from higher-end radeon X800 and X850 parts. Naturally, this gives these boards a decent legacy to build themselves on, featuring Vertex Shader 2.0 and Pixel Shader 2.0b support, as well as a full complement of six vertex shaders found in these parts. The only cut-down aspect of these boards compared to their bigger brothers is, naturally, the number of pipelines - Down to eight from the sixteen found on the high-end parts. The default clocks for the Radeon X800GT are 475MHz for the core, and 490MHz DDR for the memory, and it is these very clock speeds which we find on the Powercolor board we are looking at today.
